Application Q: How do I record from both the Guitar and Mic inputs at the same time on the JM-4 Looper? A: You can only record from either the Guitar input or the Mic/Aux input using the Record Select button on the left side of the pedal, but not both at the same time. The AUX input can be routed to be recorded in conjunction with either the Guitar input for guitar amp and effect processing, or the Mic input with the vocal processing effects by holding down the Record Select button, then selecting your routing option from the screen. Known Issues -Quick Capture = Hold the UNDO switch and then hold down REC switch (not REC + UNDO as it is silkscreened on the unit). In other words, first step on UNDO switch and keep it held down while also stepping on REC switch. -The "Clip" LED lights up upon powering up the JM-4. This is normal power-up behavior. -Some of the Artist/Song Presets from the original Spider III release were not included in the JM-4 release due to space restrictions. -The Guitar Tone Presets (70's sounds by Song Title) are simply guitar tones. They are not backing tracks. The backing tracks on the JM-4 are original compositions written and recorded by studio musicians specifically for Line 6 Spider Jam and JM-4 products.

The Looper How do I find the Looper? Most factory presets already have a Looper block, ready to go. If your preset doesn't, or you cleared all the blocks, Looper blocks can be selected from the very bottom of the Model List, below the Send/Return category. How much looping time do I get? For mono looping, Helix gives you up to 120 seconds 1/2-speed or 60 seconds full speed. There’s also a new stereo looper, which gives you 60 seconds 1/2-speed or 30 seconds full speed. Why does the Looper stop when I switch presets? Helix's looper can maintain playback and recording across presets as long as the target preset: Has the same type of looper block (mono or stereo) Has the looper block on the same path (1 or 2) Has the looper block assigned to a footswitch Otherwise, loop recording/playback will stop. Basic Looper Usage Helix can add one mono or stereo Looper block per preset. The Looper can exist anywhere on either Path 1 or Path 2. See Looper Footswitch Mode for information on using the Looper. Using a Dual signal path: Keep in mind that the looper is only available for one signal path at a time. So if you're using a second signal path, you will noticed a significant drop in volume, since the looper is only on one path. Looper Settings Knob Parameter Description 1 Playback: Adjusts looper playback level. You may find it useful to turn this down a bit so your live guitar can be slightly louder. 2 Overdub:Sets the level of your loop while overdubbing. For example, if your Overdub Level is set to 90%, each time your loop repeats, its volume will be reduced by 10%, sounding quieter and quieter with each overdub pass. 3 Low Cut and Low Cut: Filters a portion of the loop's bass and/or treble frequencies, which can improve the mix with your live guitar.
